What is a Bigha Land Calculator?
A Bigha Land Calculator is a specialized tool for converting land area measurements between Bigha and other units such as Katha, Decimal, Acre, Square Feet, Square Meter, and Hectare. Bigha is a traditional land measurement unit widely used across South Asia, particularly in Bangladesh, West Bengal, Assam, Nepal, and other Indian states.
Because the value of 1 Bigha varies by region — for example, 1 Bigha equals 14,400 sq ft in Bangladesh, West Bengal, and Assam, but 72,900 sq ft in Nepal — this calculator lets you select your regional standard for accurate results.
The tool also supports a Custom mode where you can define your own Bigha value in square feet, making it flexible for any regional variation not covered by the presets.
